“…In particular, Shang and others [11] investigated secure communications in a cooperative network that included hybrid relay (HR) wireless power, in which an intruder attempts to capture the data transmitted between a user and the HR. In Singh and others [13], the performance of a relay‐assisted wireless network over fluctuating fading channels was evaluated. However, a possible drawback of relay‐assisted MIMO systems is the complexity of detection, which is caused by the number of antennas used, such as in future massive MIMO (mMIMO) systems [14].…”

This paper presents the performance evaluation of an amplify‐and‐forward (AF) relay‐assisted multiuser multiple input–multiple output (MU–MIMO) downlink transmission system for correlated fading channels. The overall system performance was improved by incorporating a double‐quadrature spatial modulation (DQSM) scheme. The bit error rate (BER) performance and detection complexity of the AF–MU–MIMO–DQSM system were analyzed and compared with those of a conventional AF–MU–MIMO system under the same conditions and parameters. The results showed that the correlated fading channel severely affected the performance of systems with higher spectral efficiency (SE). Considering an SE of 12 bpcu/user, the AF–MU–MIMO–DQSM system yielded a gain of up to 3 dB in BER performance compared with that of its conventional counterpart for the analyzed cases. In terms of detection complexity, the AF–MU–MIMO–DQSM system showed a reduction of up to 56 % compared with that of the conventional system for the optimal maximum likelihood detection criterion.
